TNI/ENTOR ATTORNEYS 3,068,560 MEANS FOR FITTING (CABLE AND LIKE BINDING R MOUNTING CLIPS, 1 Edgar Frank Emery, Sharston Works, Leestone Road, Wythenshawe, Manchester 22, England Filed July 9, 1959, Ser. No. 826,030 Claims priority, application Great Britain July 19, 1958 6 Claims. (til. 29-267) This invention relates to means for fitting cable and like binding or mounting clips, and is more particularly concerned with binding or mounting clips of the type (hereinafter called of the type described) comprising a ring-like member of resiliently extensible material, and a hook-ended connecting member. Examples of such binding or mounting clips are described in the specification of our prior application Serial No. 384,461, new Patent No. 2,896,818. The binding clip is employed by abutting a bundle of cables or the like against the connecting member and passing the ring-like member (which may be removably attached at one side of the connecting member or may be permanently attached thereto) over the cable bundle, thereafter engaging it over a hook on the hook-ended connecting member to bind the cable bundle tightly.

The connecting member may be shaped so as to permit it to be mounted or secured to a support, if desired, for example to enable the clips to be employed for bundling cables, wires and the like to a mounting board.

To ensure tight binding of the cables or the like, it is desirable to employ ring-like members which require considerable stretching to enable them to be engaged over the hook-like member in the fitting thereof and where the ring-like members are made of polyvinyl chloride or like plastic material such stretching is extremely difficult.

The object of this invention is to provide a device enabling such stretching and fitting of the ring-like mem- 'bers to be effected simply, quickly and with the minimum of effort.

With this object in view, the present invention provides means for facilitating the stretching and engaging of the ring-like member of a cable or like binding or mounting clip of the type described with the hook-ended member thereof comprising a lever which has, at one end, a loop-like element, said element being of a relatively inextensible material.

Preferably the loop-like element is in the form of a pair of projecting arms between which extends a thin straight cross bar of such length as to enable it to be inserted through a ring-like member and be engaged with a hook of the hook-like member.

The means aforesaid may conveniently be moulded from a comparatively rigid plastic such as nylon, and to ensure adequate stretching of the ring-like member, the projecting arms may conveniently be divergent, towards the cross-bar.

The invention will be described further, by way of example, with reference to the accompanying drawings showing one embodiment thereof and in which:

FIG. 1 shows in front elevation one device constructed in accordance with the present invention;

FIG. 2 is a section along line 11-11 of FIG. 1;

FIG. 3 is a section along line III-HI of FIG. 1;

FIG. 4 shows diagrammatically the use of the device illustrated in FIGS. 1 to 3; and

FIG. 5 shows an alternative form of device, such device having a web formation between the arms thereof.

Referring now to FIGS. 1 to 3 of the drawings which show a device for facilitating the stretching and engaging of the ring-like member of a cable or like binding or mounting clip of the type described comprises an elongated hand lever 11 made of moulded plastic of a comparatively tough and inextensible, forexampleof nylon.

.sIntegral with the lever at one end thereof are a pan of projecting arms 12a, 12b, these being spaced apartat their roots where they connect with the lever 11, and diverging away from said lever. A cross bar 13 connects the ends of the projecting arms 12a, 12b remote from the lever 11. The arms 12a, 12b and the cross bar 13 are of circular cross-section and comparatively thin, for example approximately two millimetres in diameter.

Such device renders remarkably simple the fitting of the ring-like members of cable binding or mounting clips of the type described. The use of the device is illustrated in FIG. 4 and as shown in this figure the ring-like member 14 of a cable mounting clip 15 engages with a hook 16a of the hook-ended connecting member 16 after passing the ring-like member 14 around a wire bundle 17. Such assembly is effected by inserting the cross bar 13 and arms 12a, 12b of the device through the ring 14 and engaging the cross bar 13 with the hook 16a. Thereafter, the whole device is pivoted about the hook 16a so as to stretch the ring-like member 14 and the latter tends to slide down the arms 12a, 12bto engage easily over the hook 16a, and disengaging the arms 12a and 12b and cross bar 13 from the ring-like member 14, so that it can be removed from the clip.

Strengthening ribs may be provided between the arms if required, and it has been found convenient to provide a web 18 between the arms and the lever disposed adjacent the roots of said arms, and such an arrangement is shown diagrammatically in FIG. 5.

The invention is not confined to the precise details of the foregoing example, and variations can be made thereto. For instance, the lever can be of any shape facilitating the manipulation thereof, and the handle and arms and cross bar can be made of materials, other than plastics, although a relatively inextensible plastic material such as nylon is particularly suitable since its resilience is conducive to ensuring adequate stretching of the ring-like member and subsequent withdrawal of the arms and cross bar.

Further, the arms may be parallel or convergent if r quired.

I claim:

1. A tool for facilitating the stretching of a stretchable ring of a cable or like binding clip, said clip being 'arcuate and having a hook of substantial width at on end, said ring adapted to engage said clip and to be stretched over said hook, said tool comprising an inextensible flexible elongated lever, a pair of spaced arms integral with said lever extending from one end of said lever adjacent the side edges thereof, a cross bar integral with and connecting the ends of said arms, the length of said cross bar being greater than the width of said lever, the distance between said arms at their ends being greater than the inside width of said ring when unstretched, the length of said cross bar being at least equal to the width of said hook, whereby said ring is adapted to be stretched and widened by the action of said lever to fit over said hook and then released from said lever to become anchored in said hook.

2. A tool as set forth in claim 1 in which said ring is rectangular.

3. A tool as set out in claim 1 in which said arms and cross bar are of nylon.

4. A tool as set forth in claim 1 in which the edges of said lever are provided with ribs.

5. A tool as set forth in claim 1 in which the crosssection of said arms and cross bar is circular.

6. A tool as set forth in claim 1 in which the arms have a web therebetween adjacent to the anchor of said arms to said lever.
